Watch The Heartwarming Moment This Rescue Dog Tries A Bed For Very First Time.

When you've always had something, it's easy to take it for granted. Take, for example, your bed. You come home to it every night (and you probably always have), but when you do, you don't think about it too much. It's just another thing in your home, right? Well, for Millie, a bed isn't just unusual: It's basically the most exciting thing ever.

Millie is a 7-year-old bull terrier foster dog who has never had a real bed. When she finally discovers the joy of lying on one, her excitement is palpable. We've never seen a creature quite so ecstatic before.
